Default Desk Top Dyno help PLEEZ

Current Set Up: 350 (8.5 Comp), Comp260H Cam, Stock 76cc heads, 1.5 Roller Tip Rockers, Dual Plane Intake, Stock Q-Jet, Dynomax Ceramacoat Headers, 2 1/2" Chambered Pipes..........Coming this winter: 58cc heads with same sized valves. Could someone pleez run this combo thru both ways (b4 and after new heads) so I can see what to expect with next mod? 58cc heads should bump me up to 10.0+ on compression ratio... Thanx in Advance.......This Place Rocks........... :cheers: :cheers: :cheers:

What 58cc heads? vortech? Changing the heads will alter the numbers.
Here's original setup. There is no way in this program to adjust for particular manifolds or roller rockers.

Those are heads off of an 80-86 305 with 1.84 intake and 1.50 exhaust valves,
going to 58cc brings compression to 10.24:1
